The value error and encoding error when processing JSON in Python solve the real-time recording problem.

This article mainly introduces two methods to solve the real-time recording problem: the value error when processing JSON and the encoding error. here, I suggest using Python 3.x, python3's default Unicode encoding can save us a lot of trouble in actual use. For more information, see 1. ValueError: Invalid control character at: line 1 column 8363 (char 8362)
When json. loads (json_data) is used, the following error occurs:

ValueError: Invalid control character at: line 1 column 8363 (char 8362)

The error occurs because the string contains the carriage return (\ r) or line feed (\ n)
Solution:
(1) escape these characters:

json_data = json_data.replace('\r', '\\r').replace('\n', '\\n')

(2) use the keyword strict:

json.loads(json_data, strict=False)

Strict is True by default. it strictly controls internal strings and sets it to False to allow \ n \ r.

2. UnicodeEncodeError: ascii codec can't encode error
Run the python script written in windows in linux and report it directly:

UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-11: ordinal not in range(128)

The cause of the error is that during installation of Python2.7, the default encoding is ascii. when non-ascii encoding occurs in the program, this error is often reported during Python processing, however, this problem does not occur in Python3.
Solution:
(1) temporary solution:
Add:

import sys reload(sys) sys.setdefaultencoding('utf8')

(2) once and for all:
Create a new sitecustomize. py in the lib \ site-packages folder of Python. the content is as follows:

# encoding=utf8 import sys reload(sys) sys.setdefaultencoding('utf8')

In this case, when the system starts Python, it calls the file and sets the default encoding of the system.
